Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a new type of fan wheel disc. Background Technique

[0002] The working principle of a fan is to use the power of a motor to drive the wheel disc to rotate rapidly. The wind disc generates a large amount of air flow through rotation. When the air flow passes through the wind disc and the blades, it will be guided by the blades to form a certain pressure difference, and then generate a relatively high wind speed and wind pressure. This pressure difference pushes the air flow into the air duct and finally outputs it to the outside. As the core component of the fan, the strength and stability of the wheel disc have an important impact on the efficiency of the entire wind energy conversion system.

[0003] Fans usually work in the open air environment. When encountering extreme weather such as strong winds, since the existing blades are usually directly connected to the wheel disc by means of plugging or welding, when the wind speed suddenly increases or the wind direction changes sharply, the force received by the blades will change rapidly, resulting in uneven stress on the blades. This uneven stress will be transmitted to the wheel disc. Especially when the force received by the blades exceeds its design limit, it will generate excessive stress on the wheel disc, resulting in deformation or damage of the wheel disc. The deformation or damage of the wheel disc caused by uneven stress is not conducive to the long-term use of the wheel disc.

[0004] Therefore, this application provides a new type of fan wheel disc. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of fan wheel disc to solve the problems raised in the background technique.

[0006] The embodiment of this application provides a new type of fan wheel disc, including a wheel disc. A hub is fixedly installed in the middle of the wheel disc. A number of groups of slots are opened on the outside of the wheel disc. Blades are inserted at the slots on the outside of the wheel disc. A reinforcing ring is fixedly installed on the side wall of the wheel disc. One ends of a number of groups of the blades are in contact with the reinforcing ring. Lateral support mechanisms are installed on both sides of a number of groups of the blades outside the reinforcing ring. The lateral support mechanism includes a first fixing block. The first fixing block is fixedly installed on the outside of the reinforcing ring. A spring is installed on the side of the first fixing block away from the reinforcing ring. The top of the spring is installed with a second fixing block. The end of the second fixing block away from the spring is in contact with the blade.

[0007] By adopting the above technical solution, several groups of blades are in contact with the strengthening ring. When the blades are subjected to different forces under the action of wind, the strengthening ring can provide an additional supporting force to help disperse and balance these forces, thereby enhancing the rigidity and strength of the wheel disc. At the same time, when the blades rotate at high speed, the wheel disc will be subjected to the lateral force of the blades. The blades drive the second fixing block to squeeze the spring, and the spring generates a certain elastic deformation, thereby absorbing and buffering these lateral forces, reducing the deformation of the wheel disc caused by uneven force, and being beneficial to the long-term use of the wheel disc.

[0008] Optionally, a telescopic guide rod is placed inside the spring. One end of the telescopic guide rod is installed on one side of the first fixing block, and the telescopic end of the telescopic guide rod is installed on one side of the second fixing block.

[0009] By adopting the above technical solution, when the spring generates elastic deformation, the telescopic guide rod synchronously expands and contracts to play a guiding role in the elastic deformation of the spring, thereby being beneficial to improving the service life of the spring.

[0010] Optionally, a number of reinforcing ribs are fixedly installed on the back surface of the wheel disc.

[0011] By adopting the above technical solution, the strength of the wheel disc is enhanced by the reinforcing ribs, which is beneficial to improving the service life of the wheel disc.

[0012] Optionally, the number of the reinforcing ribs is the same as that of the blades, and the reinforcing ribs and the blades are symmetrically arranged.

[0013] By adopting the above technical solution, each blade has a symmetrically corresponding reinforcing rib on the back surface of the wheel disc, thereby maximizing the supporting effect of the reinforcing ribs on the blades and the wheel disc structure.

[0014] Optionally, rubber layers are fixedly installed at several groups of slots on the outside of the wheel disc, and the rubber layers are in contact with the outer walls of the blades.

[0015] By adopting the above technical solution, the rubber layers reduce the noise and vibration generated by the rotation of the blades during the operation of the fan, improving the practicality during use.

[0016] Optionally, several groups of connecting holes are opened inside the wheel disc outside the hub.

[0017] By adopting the above technical solution, when this device is connected to power equipment such as a motor, bolts, etc. are used to pass through the connecting holes to connect with the power equipment such as a motor, thereby improving the fixing effect during the installation of this device.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] 1. Through several groups of blades abutting against the reinforcing ring, when the blades are subjected to different forces under the action of wind, the reinforcing ring can provide an additional supporting force to help disperse and balance these forces, thereby enhancing the rigidity and strength of the wheel disc. At the same time, when the blades rotate at high speed, the wheel disc will be subjected to the lateral force of the blades. The blades drive the second fixing block to squeeze the spring, and the spring produces a certain elastic deformation, thereby absorbing and buffering these lateral forces, thus reducing the deformation of the wheel disc caused by uneven force and being beneficial to the long-term use of the wheel disc.

[0020] 2. When the spring produces elastic deformation, the telescopic guide rod synchronously expands and contracts to play a guiding role in the elastic deformation of the spring, thereby being beneficial to improving the service life of the spring. Brief Description of the Drawings

[0028] In this technical solution, several groups of blades 3 are in contact with the reinforcing ring 4. When the blades 3 are subjected to different forces under the action of the wind, the reinforcing ring 4 can provide an additional supporting force to help disperse and balance these forces, thereby enhancing the rigidity and strength of the wheel disc 1. At the same time, when the blades 3 rotate at high speed, the wheel disc 1 will be subjected to the lateral force of the blades 3. The blades 3 drive the second fixing block 503 to squeeze the spring 502, and the spring 502 undergoes a certain elastic deformation, thereby absorbing and buffering these lateral forces, reducing the deformation of the wheel disc 1 caused by uneven force, and being beneficial to the long-term use of the wheel disc.

[0029] In some technical solutions, such as Figure 4 As shown, a telescopic guide rod 7 is placed inside the spring 502. One end of the telescopic guide rod 7 is installed on one side of the first fixing block 501, and the telescopic end of the telescopic guide rod 7 is installed on one side of the second fixing block 503.

[0030] During use, when the spring 502 undergoes elastic deformation, the synchronous expansion and contraction of the telescopic guide rod 7 play a guiding role in the elastic deformation of the spring 502, thereby being beneficial to improving the service life of the spring 502.

[0031] In some technical solutions, such as Figure 3 As shown, several groups of reinforcing ribs 6 are fixedly installed on the back of the wheel disc 1.

[0032] During use, the strength of the wheel disc 1 is enhanced by the reinforcing ribs 6, which is beneficial to improving the service life of the wheel disc 1.

[0033] In some technical solutions, such as Figures 1 - 3 As shown, the number of the reinforcing ribs 6 is the same as that of the blades 3, and the reinforcing ribs 6 and the blades 3 are symmetrically arranged.

[0034] During use, each blade 3 on the back of the wheel disc 1 has a symmetrically corresponding reinforcing rib 6, thereby maximizing the supporting effect of the reinforcing rib 6 on the blades 3 and the structure of the wheel disc 1.

[0035] In some technical solutions, such as Figure 2 As shown, rubber layers 8 are fixedly installed at several groups of slots outside the wheel disc 1, and the rubber layers 8 are in contact with the outer walls of the blades 3.

[0036] During use, the rubber layers 8 reduce the noise and vibration generated by the rotation of the blades 3 during the operation of the fan, improving the practicability during use.

[0037] In some technical solutions, such as Figure 3 As shown, several groups of connection holes 9 are opened outside the hub 2 inside the wheel disc 1.

[0038] When in use, when connecting this device to a power device such as a motor, bolts or the like are used to pass through the connection holes 9 to connect to the power device such as a motor, thereby improving the fixing effect during the installation of this device.

[0039] Working principle: Through a number of groups of blades 3 abutting against the reinforcing ring 4, when the blades 3 are subjected to different forces under the action of wind, the reinforcing ring 4 can provide an additional supporting force to help disperse and balance these forces, thereby enhancing the rigidity and strength of the wheel disc 1. At the same time, when the blades 3 rotate at high speed, the wheel disc 1 will be subjected to the lateral force of the blades 3. The blades 3 drive the second fixing block 503 to squeeze the spring 502, and the spring 502 generates a certain elastic deformation, thereby absorbing and buffering these lateral forces, so as to reduce the deformation of the wheel disc 1 caused by uneven force, which is beneficial to the long-term use of the wheel disc. When the spring 502 generates elastic deformation, the telescopic guide rod 7 synchronously expands and contracts to play a guiding role in the elastic deformation of the spring 502, which is beneficial to improving the service life of the spring 502. The strength of the wheel disc 1 is enhanced by the reinforcing ribs 6, which is beneficial to improving the service life of the wheel disc 1. There is a reinforcing rib 6 symmetrically corresponding to each blade 3 on the back of the wheel disc 1, so as to maximize the supporting effect of the reinforcing rib 6 on the blades 3 and the structure of the wheel disc 1. The noise and vibration generated by the rotation of the blades 3 during the operation of the fan are reduced by the rubber layer 8, improving the practicability during use. When connecting this device to a power device such as a motor, bolts or the like are used to pass through the connection holes 9 to connect to the power device such as a motor, thereby improving the fixing effect during the installation of this device.
